Build failed: Sprockets::FileNotFound: couldn't find file

I get this error while building a Rails 7 application (that was upgraded from previous rails versions):

-----> Preparing app for Rails asset pipeline
       Running: rake assets:precompile
       rake aborted!
       Sprockets::FileNotFound: couldn't find file 'emojionearea/dist/emojionearea' with type 'text/css'

The problem is that you should run rake yarn:install BEFORE rake assets:precompile... otherwise some assets are not present.

Can you fix this?

Note: I am using "heroku/buildpacks:20" because "heroku/buildpacks:22" does not exist here...

We only run the rake assets:precompile we don't run rake yarn:install. If you need that it's up to you to hook into the rake tasks chain. That's how gems like webpacker work, they enhance the rake task.
